IMPROVEMENT IN TIME-LOCKS FOR SAFES.

Specification forming part of Letters Patent No. 206,678, dated August6, N79; application filed May 15, 1379.

To all whom it may concern:

Be it known that we, W M. KOOK and J o- SEPH L. HALL, of Cincinnati, inthe county of Hamilton and State of Ohio, have invented certainImprovements in Time-Looks for Safes, &c., of which the following is aspecification:

Our invention consists in a novel construction and arrangement of a mainlock and an additional lever for dogging the bolt-work of a safe orvault door, whereby the main lock and additional lever may be operatedwhether the time-movement be running or not; and it further consists incombining with said dogginglever an adjustable stop and a guard-lock,arranged to release the dogging-lever in case the time attachment stopsor fails to operate, all as hereinafter more fully described.

Figure l is an elevation of the inner face of a section of a safe orvault door, showing our invention applied thereto, with the face-plateof the main lock detached. Fig. 2 is a similar view with the lock-platein place. Fig. 3 is a side elevation of the sectional dial used toconnect the time-movement with the other parts; and Fig. 4 is a faceview of one of the sections, shown detached.

In the drawing, A indicates an ordinary permutation-lock, made in theusual manner, with the exception that 011 the top of the rocking bar 0there is formed a projection, 0', arranged to work through an opening inthe top of the lock-case when the bolt of the lock is drawn back and thespindle turned. (See Fig. 1.

An elbow-lever, E, is pivoted to the door with one end pivoted to thebolt-work and has its other end arranged so as to be locked in positionby the bolt D of the main look when said bolt is thrown forward, thisbeing a common arrangement. Directly over the look A we pivot adogging-lever, L, in such a position that, when down, its front end willrest directly in rear of the stud on the bar 13, which is rigidlyconnected to the train-bolts, and thereby securely dog the bolt-work,even though the bolt D of the lopk be retracted, as represented inFig. 1. Upon the under ide of this lever L, at a point directly overt heopening in the lock-case, there is a projection, e, as shown in Figs. 1and 2, against which the projection 0 on the rocking bar strikes as thelatter rides upon disk I after drawing back the bolt 1) of the lock,thereby elevating the front end of the dogging-lever L, and thusundogging the bolt-work, as shown in Fig. 2.

It will be observed that the disk F will operate to draw back the bolt Dfar enough to release the elbow-lever E, and thereby release theb0lt-work. so far as the main lock is concerned, before it raises theangle-bar far enough to elevate the dogging-lever L, but that as thedisk F continues its movement it lifts the angle-bar, thereby elevatingthe dogging-lever L, thus freeing the bolt-work from both.

It will thus be seen that when there is nothing to hold down the lever Lthe bolt D and the lever L will both be operated by turning the spindleof the look, but that when said lever L is held down, then the spindlecan be turned only far enough to retract the bolt 1), in which case thebolt-work will still be held by the lever L.

To prevent this lever L from being operated at improper times, weconnect therewith a time-movement, as indicated at T, Figs. 1 and 2, thetime mechanism, of any suitable kind, being arranged to impart motion tothe wheel 'm, which, in turn, drives the wheel a. This wheel a isprovided with a tubular stem, on which is placed loosely a series ofsectional disks, 0, varying in width of flange, but of uniform diameter,as shown in Fig. 3, one of the Widest of these being shown detached inFig. 4. After these disks have been placed on the tube, a washer havingan arm, 4), standing at right angles to its body is slipped on also, asshown in Fig. 3, the inner end of the arm 0 resting in a hole in thewheel a, to keep it from turning, when the whole are secured by a screwwasher or nut, I. By loosening the nut 1 these sectional disks 0 can bearranged on the tubular spindle so as to form a dial of greater or lessextent, as may be de sired, they being held in place when thus arrangedby simply tightening the nut I. As shown in Fig. 4, these disks 0 areworked with figures to indicate hours or other divlsions of time, sothat they may be readily arranged to form a dial that shall be anyrequired number of hours in passing a given point, the arm 1) serving asa startmg-polnt 1n arranging the disks 0 on their stem or tube. At apoint directly under this dial, on the face of the dogging-lever L, is astud or projection, 1, as shown in Figs. 1 and 2, and to the front faceof the lever L is secured a sliding piece, 1), which is slotted to admitof being moved endwise, it having a vertical projection, I, arranged torest upon and form a continuation of the lug i when in place, as shownin Fig. 1. As this flange or projection l is of such a height as to justclear the edge of the dial carried by the wheel a, it follows that thelever L cannot be raised so long as the projecting flanges of the dialare over the stop or projection I, and the latter rests upon the stud iin the position shown in Fig. 1, which represents the condition of theseparts when the lock is closed during the night. \Vhen, however, the dialhas been turned far enough to carry its proiectingtlange past the stopI, then the lever L is free to be raised.

It, now, it be desired to leave the timemovementin operation during theday. and still have the lever I. free to be raised, so that the door canbe opened at any time, it is only necessary to shove the stop I back soit will drop down, as shown in Fig. 2, when the lever can be raised,although the projecting flange of the dial is still over it. A smallspring is applied to the stop I, to assist in holding it both when upand when down, though this is not essential.

To enable this stopl to be moved or thrown back out of the way in casethe time-move ment should stop, or for any reason should fail tooperate, a lever, I, is pivoted so as to have its upper end rest infront of the stop I, as represented in Fig. 1, while its opposite end isarranged to be operated upon by the guardlock (l, located within theease of the main lock, as shown in Fig. 1. This guard-lock isconstructed in the same manner as that described in our applicationtiled April 27, 1878, to which reference is made fora more detaileddescription.

By operating the guard-lock (i, the tumblers of which are connected toand driven by the spindle of the main lock A by pinions, (not shown,)the upper end of the lever l is thrown against the face of the stop I,which is thereby shoved back and allowed to drop down, as shown in Fig.2, when the lever L can be raised by operating the main lock, as beforedescribed, and the door opened. This guardlock is only designed to beused in case the time-movement fails to operate; and hence thecombination on which its tumblers are set is not designed to be known tothose in daily charge of the safe or vault, but is to be kept by someother party, and, if desired, at some other place, and is to be changedas often as it is used, as an additional means of security both againstburglars and dishonest employes.

In this as in my former application, above mentioned, the cap or faceplate of the guardlock is so arranged that it can only be removed by aknowledge of the combination on which its tumblers are set, and thus alltampering with them is prevented.

It is obvious that, instead of making a projection on both the lever Land the rocking bar C, it may be made on either one alone by increasingthe size.

It will be seen that by means of the sectional dial the time attachmentcan be adjusted to operate for a greater or less time, according as itmay be arranged, and that by setting or turning the dial so that sometime will elapse before its projectin g flange is brought over the stopI, it will be possible to open the door in the ordinary manner until thetime arrives when the flange is over the stop, after which it cannot beopened until the time for which the movement was set shall have arrived,unless the gnard-lock be operated to remove the stop I. This enables theperson having charge of the safe or vault to close and lock it in theordinary way, and still be able to open it up to the moment when theprojecting flange of the dial shall begin to pass over the stop I; andby adjusting the sections properly this period of time maybe made longor short, as desired, and may be varied from day to day, and yet allowthe safe to be opened at the same hour in the morning each day, thetime-movement coming automatically into operation at the appointed time,and so continuing in operation until the next day at the appointed hour.

\\'e do not in this application make a claim for the use of aguard-lock, broadly, nor for the manner of securing the cap or faceplate of the same, as these features are shown in our n'eviously-tiledapplication.

liaving thus described our invention, what we claim is 1. In combinationwith the pivoted or dog ging lever L, the main lock A, having itsrocking bar arranged to operate or raise the lever by means of aprojection on one or both, substantially as described, whereby the boltot' the main lock and the lever L can both be disconnected from thebolt-work by operating the main look, as set forth.

2. The main lock A and the pivoted lever L, provided with an adjustablestop, I, in combination with the dial It, the said parts being arrangedto operate substantially as described, whcreby the lever can be retainedin position to dog the bolt'work even when the bolt of the main lock iswithdrawn, or, it desired, can be released even when the time attachmentis in operation.

3. The combination of a time attachment provided with the dial R, thelever L, provided with the adjustable stop I, the main lock A, and theguard loek (l, with the lever I, all arranged to operate substantiallyas described, whereby the parts can be released and the door unlocked incase the time attachment stops or fails to operate.
